Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a data record created in a certain system, which is used to determine whether or not there is a portion that causes a data exception due to an attribute error when the data record is used in another system. The present invention relates to a data check device to be checked.

[0002]

2. Description of the Related Art When a data record created in a certain system A is used in another system B, the structure of a reference data record recognized by the system B (attribute of each item in the data record, item length, etc.). ) Based on the system A
It is necessary to check in advance whether or not the check target data record created in step 1 has a part that causes an attribute error with respect to the reference data record.

Conventionally, as a technique for checking whether or not a part of the data record to be checked has an attribute error with respect to the reference data record, an item attribute and an item length of each item of the reference data record are conventionally included. The item definition information is stored in the external storage device, and when the data record is checked, the check target data record is read, and the item definition information is expanded on the main storage device, and the check target data read based on the item definition information is read. A technique (for example, Japanese Patent Laid-Open Publication No. Sho 59-148921) for checking whether or not a part causing an attribute error exists in a record is known. Check if the record has any attribute error with respect to the reference data record It can be. That is, the item attribute and item length of each item of the reference data record recognized by the system B may be stored in the external storage device as item definition information.

[0004]

By the way, when performing the attribute check of a data record, it may be sufficient to perform the attribute check only for a specific attribute. For example, a test of a function related to the data record processing of the system B is performed using a data record already created in the system A because the data record created in the system B does not exist. If it is recognized that the data record includes only two types of attributes, namely, a numeric item and an alphanumeric item, the data record created by the system A (the items in this data record are , Numeric, alphanumeric, or zero suppression), it is sufficient to perform an attribute check only on those parts of the system B that recognize that the attribute is a number. It is.

That is, when the attribute recognized by the system B as a numeral is recognized by the system B, and when the attribute is recognized by the system A as an alphanumeric character and zero suppression, the data record created by the system A is added to the above described portion. In some cases, a code other than a number may be stored, and when a test of the system B is performed using such a data record, the test is interrupted due to the occurrence of a data exception. The parts that are recognized as alphanumeric characters are
This is because a data exception does not occur even if you recognize that the attribute is numeric or zero suppress.

As described above, even if it is sufficient to perform an attribute check only on a specific attribute of a data record, the above-described conventional technique sets the item attributes and item lengths of all items of the reference data record. Since the data is stored in the external storage device, the attribute check is performed for all the items. That is, the attribute check is performed even for unnecessary items, which causes a problem of wasteful processing time. Further, in order to eliminate such a problem, it is conceivable to store only the item attribute, item start position, and item length of the item that needs to be attribute checked in the external storage device. The attribute, start position, and item length of the item that needs to be checked must be obtained by analyzing the record structure definition information, which causes a problem of burdening the user.

Therefore, an object of the present invention is to provide a data check device capable of performing an attribute check only on a specific attribute in a data record without burdening the user.

[0008]

According to the present invention, in order to achieve the above object, the attribute, start position, and item length of each item in the reference data record are determined based on record structure definition information indicating the structure of the reference data record. A record structure analysis unit for creating record structure definition development information to be shown, based on the check attribute specified in the check operation specification parameter description and the record structure definition development information created by the record structure analysis unit, A parameter analysis unit for obtaining a position in a record for performing a check, a data reading unit for reading data records one by one from a file in which the data record to be checked is stored, and a data reading unit for reading the contents of the data records read by the data reading unit. Among the records in the record determined by the parameter analysis unit A check target portion acquisition unit for acquiring the content, in which a attribute check unit for performing attribute checks the contents of the check target portion acquisition unit has acquired.

In order to achieve the object of allowing a user to recognize the data record to be checked having an attribute error, the item name of the reference data record corresponding to the attribute error portion, and the content of the attribute error portion, the attribute checking section is provided. And outputs the relative number of the data record to be checked including the part where the attribute error was detected, the item name of the reference data record corresponding to the part where the attribute error was detected, and the content of the part where the attribute error was detected. It is provided with a result output control unit.

Further, according to the present invention, even if a data record created in a certain system includes a portion which causes a data exception due to an attribute error when the data record is used in another system, the above-mentioned certain system In order to achieve the purpose of making it possible to create a data record that can be used in tests on other systems from the data record created by the above, the result output control unit is For the check target data record for which the attribute error was not detected, the data record is output as it is to the output data file. This is to output to the output data file after changing the content without attribute error.

[0011]

The record structure analysis unit creates record structure definition development information indicating the attribute, start position and item length of each item in the reference data record based on the record structure definition information indicating the structure of the reference data record, The analysis unit obtains a position in the data record to be checked in the check target data record based on the check attribute specified by the check operation specification parameter description and the record structure definition development information created by the record structure analysis unit.

At the time of checking the data record, the data reading unit selects the data record to be checked from the file as 1
Read record by record.

When the data reading unit reads one data record to be checked, the part to be checked acquisition unit
Among the contents of the data record, the contents of the position in the record obtained by the parameter analysis unit are acquired.

When the check target part acquisition unit acquires the content of the item to be checked, the attribute check unit performs an attribute check on the content of the item. In addition, the result output control unit determines the relative number of the check target data record including the part in which the attribute error is detected by the attribute check unit,
An item name of the reference data record corresponding to the part where the attribute error is detected and the contents of the part where the attribute error is detected are output.

In another configuration, for the check target data record for which no attribute error is detected by the attribute check unit, the data record is directly output to the output data file, and the attribute check unit outputs the attribute error. For the check target data record in which is detected, the content of the portion in which the attribute error is detected is changed to the content without the attribute error, and then output to the output data file.

The result output control section 20 has a function of outputting a check result and the like according to the contents of the outline information flag and the operation flag stored in the parameter expansion table 16.

Next, the operation of this embodiment will be described.

Now, for example, is it possible to test the function relating to the data record processing of the system B by using the data record already created in the system A because the data record created in the system B does not exist? In order to check whether or not the data check device 1 is used, consider the case where the attribute check of a data record created in the system A is performed using the data check device 1.

In this case, the operator first inputs the record structure definition information 2 indicating the structure of the reference data record recognized by the system B to the record structure input section 11.

When the record structure definition information 2 is input to the record structure input unit 11, the record structure analysis unit 12
As shown in the flowchart of FIG. 6, one sentence in the input record structure definition information 2 is read (step S1), and the syntax of the sentence is analyzed (step S3).

If the read sentence has a syntax error (YES in step S4), an error message is displayed on the display device 7 (step S6), and then the process ends. If there is no syntax error (step S4 is N
O) generates record structure definition expansion information about the item defined by the read statement and expands it in the record structure definition expansion table 13 (step S).
5).

The processing in step S5 will be described in detail as follows. That is, if the read sentence defines an elementary item, record structure definition expansion information including the item name, attribute, start position, and item length of the item defined by the sentence is generated and generated. The developed record structure definition development information is developed in an area corresponding to one table number in the record structure definition development table 13. Here, the start position of the item is set to “0” if the read sentence is for the first item, otherwise, the start position of the item in the record structure definition expansion information previously expanded in the record structure definition expansion table 13 is set. , A value obtained by adding the item start position and the item length.

If the read sentence defines a group item, the item length of the group item cannot be obtained unless the item lengths of all the items in the group item are known. At the time when the statement that defines the item is read, only the item name, attribute (always alphanumeric X), and start position are generated from the record structure definition expansion information of the group item, and these are defined in the record structure definition. Deployment table 13
Expanded in the area corresponding to one of the table numbers, the item length is obtained by adding all the item lengths of the items included in the group item at the time when the item lengths are known, It is developed in the above-mentioned area of the record structure definition development table 13.

Thereafter, the record structure analysis unit 12 reads one next sentence in the record structure definition information 2 (step S1), and performs the same processing as described above for that sentence. The record structure analysis unit 12 performs the above-described processing for all the sentences in the record structure definition information 2 (YES in step S2), and after displaying normal end on the display device 7 (step S7), the processing thereof. To finish.

Therefore, assuming now that the contents of the record structure definition information 2 are those shown in FIG. 2, the following processing will be performed.

The record structure analysis unit 12, when reading the first sentence "02 PKEY." Of the record structure definition information 2 (step S1), performs a syntax analysis (step S).
3). Since the syntax of this sentence is correct, the decision result in the step S4 is NO, and the process in the step S5 is performed.

Since this statement defines a group item, as shown in FIG. 3, the record structure analysis unit 12 sets the item name “PKEY”, the attribute “X”, and the start position “0” in the record structure definition. It is stored in the area of table number 1 of the development table 13 (step S5).

Next, the record structure analysis unit 12
The third sentence "03 store number PIC 9 (3)." Is read (step S1). The second sentence defines an elementary item.
As shown in, the item name “store number”, the attribute “9”, the start position “0”, and the item length “3” are expanded in the area of table number 2 of the record structure definition expanding table 13 (step S
5).

After that, the record structure analysis unit 12 reads the third sentence "03 Customer number PIC9 (8)." (Step S1). Since the third sentence also defines the basic item, the record structure analysis unit 12 uses the structure shown in FIG.
As shown in (5), the item name "customer number", attribute "9", start position "3", and item length "8" are developed in the area of table number 3 of the record structure definition development table 13 (step S5).

Next, the record structure analysis unit 12 causes the fourth
The second sentence "02 Kana customer name PIC X (20)."
Is read (step S1). Since the fourth sentence also defines the basic item, the record structure analysis unit 12
As shown in FIG. 3, in the area of table number 4 of the record structure definition expansion table 13, the item name “Kana customer name”, the attribute “X”, the start position “11”, the item length “20”.
Is set, and at the time when the fourth sentence is read, it is known that the first sentence defining the group item has been closed. The item lengths "3" and "8" of the item indicated by the second sentence are added, and the addition result "11" is developed in the area of table number 1 of the record structure definition development table 13 as the item length of the group item (step S5).

Thereafter, the record structure analysis unit 12 sequentially reads the fifth and sixth sentences in the record structure definition information 2 and performs the above-described processing. When the process for the sixth sentence "02 Deposit balance PIC 9 (11)." Is completed (YES in step S2), a normal completion display is displayed on the display device 7 (step S7), and then the process is executed. finish.

When the normal end display is displayed on the display device 7, the operator next inputs the check operation designation parameter description 3 into the parameter input section 14. The display device 7
If an error is displayed on the screen, the operator corrects the error in the record structure definition information 2 and inputs the corrected record structure definition information 2 again.

When the check operation specification parameter description 3 is input to the parameter input unit 14, the parameter analysis unit 15 reads one sentence in the check operation specification parameter description 3 as shown in the flowchart of FIG. Step S1
1), analyze the syntax of the read sentence (step S1)
3).

If there is a syntax error in the read sentence (YES in step S14), an error message is displayed on the display device 7 (step S15), and the process ends. Also, if there is no syntax error in the read statement
(NO in step S14) reads the next sentence in the check operation designation parameter description 3 (step S11),
The same processing as described above is performed.

When the above-described processing is performed on all the statements in the check operation specification parameter description 3, the parameter analysis unit 15 determines based on the read check operation specification parameter description 3 and the contents of the record structure definition expansion table 13. To generate check operation specification parameter expansion information and expand it in the parameter expansion table 16
(Step S16) Then, a normal end display is performed on the display device 7 (Step S17).

FIG. 8 is a flowchart showing details of the processing in step S16 in FIG. 7, and reference is made to step S1 in FIG.
The process of 6 will be described below.

First, the parameter analysis unit 15 refers to the record structure definition expansion table 13 and stores an area in the record structure definition expansion table 13 in which the same attribute as the check attribute specified by the check operation specification parameter description 3 is stored. All the table numbers, and set the obtained table numbers in the parameter expansion table 16
(Step S21).

Next, the parameter analysis unit 15 sets a comparison target in the parameter expansion table 16. For example,
If a numeric value is specified as the attribute of the item to be checked, illegal decimal is set as the comparison target (step S22).

Thereafter, the parameter analyzer 15 determines whether or not the output of the summary information is specified in the check operation specification parameter description 3. If the output of the summary information is specified, the parameter "15" is added to the summary information flag. "1" is set, and if not specified, "0" is set (step S2
3).

Further, the parameter analysis unit 15 checks the CLEAR statement, SELE
An operation flag is set based on the presence / absence of a CT sentence (step S24). That is, when both the CLEAR statement and the SELECT statement exist, CS is set as the operation flag, and when only the CLEAR statement exists, C is set, and S
If only the ELECT statement exists, S is set, and if neither exists, "0" is set.

Therefore, for example, if the contents of the check operation designation parameter description 3 are as shown in FIG. 4 and the contents of the record structure definition expansion table 13 are as shown in FIG. 3, the following processing is performed. Will be.

In the check operation specification parameter description 3 shown in FIG. 4, the fifth sentence "IF: DATA-ERR" specifies that the attribute to be checked is to be a number. Refers to the record structure definition expansion table 13 shown in FIG. 3, and stores the table number “2”,
“3” and “6” are set in the parameter expansion table 16 as shown in FIG. 5 (step S21).

Next, the parameter analysis unit 15 specifies that the attribute to be checked is to be a number by the fifth sentence "IF: DATA-ERR". Therefore, as shown in FIG. Unjust decimal (NUME)
Is set (step S22).

After that, since the parameter analysis unit 15 specifies the output of the outline information by the first sentence to the third sentence, the outline information flag is set to "1" as shown in FIG. Yes (step S23).

Further, since the CLEAR statement and the SELECT statement are present at the sixth and seventh positions, the parameter analysis unit 15 sets "C" as the operation flag as shown in FIG.
S "is set.

After the operator inputs the check operation designation parameter description 3, when the display device 7 displays a normal end, the data reading unit 17 using the input device 8 is displayed.
Is instructed to read the check target record storage file 4 storing the check target data records created by the system A. If an error is displayed on the display device 7, the operator corrects an error in the check operation specification parameter description 3, and inputs the corrected check operation specification parameter description 3 again.

When instructed to read the data record, the data reading unit 17 reads one data record from the check target record storage file 4 (step S31) as shown in the flowchart of FIG. It is passed to the partial acquisition unit 18 (step S33). After that, the data reading unit 17 enters a waiting state and waits for a request to read the next data record from the check target portion acquisition unit 18 (step S34).

When the data record to be checked is passed from the data reading unit 17, the check target part acquiring unit 18, as shown in the flowchart of FIG. Based on the contents of the parameter expansion table 16 and the contents of the transmitted data record, the part of the reference data record corresponding to the item part of the attribute to be checked specified by the check operation specification parameter description 3 in the reference data record 3 The contents are acquired (step S41).

The processing in step S 41 will be described in detail. First, the check target part obtaining unit 18 obtains a table number stored in the parameter development table 16. For example, if the content of the parameter expansion table 16 is as shown in FIG. 5, the check target portion acquisition unit 18 will acquire the table numbers “2”, “3”, and “6”.

Next, the check target portion acquisition section 18 refers to the record structure definition expansion table 13 based on the acquired table numbers "2", "3", "6" and stores it in the area of the table number. Acquires the item name, start position, and item length that are set. For example, if the content of the record structure definition expansion table 13 is as shown in FIG. 3, the check target portion acquisition unit 18 causes the item name “store number” and the start position “in the table number“ 2 ”to be expanded. 0 ", item length" 3 ", and item name" customer number "expanded in the area of table number" 3 ", start position" 3 ", item length" 8 "
And the item name "deposit balance", start position "43", and item length "11" developed in the area of table number "6".

After that, the check target portion acquisition unit 18
The contents of the check target part are acquired by acquiring the contents of the part indicated by the start position and item length of the acquired item in the check target data record passed from the data reading unit 17.

When the contents of the part to be checked are obtained in step S41, the part to be checked obtaining part 18 sets the contents of the obtained part to be checked, the item name in the reference data record corresponding to the part to be checked, and the current processing object. The data record to be checked is passed to the attribute check unit 19 (step S42). After that, the check target portion acquisition unit 18 enters a waiting state and waits for the attribute check unit 19 to request information about the next data record (step S43).

When the attribute check unit 19 receives the contents of the check target portion, the item name, and the data record to be currently processed from the check target portion acquisition unit 18, as shown in the flow chart of FIG. The value of the variable i indicating the number of the data record from the beginning among the data records stored in the check target record storage file 4 is set to "1" (step S51).

After that, the attribute check unit 19 acquires the comparison target from the parameter expansion table 16 and checks one of the contents of the check target portion passed from the check target portion acquisition unit 18 based on it (step S
52). For example, when the content of the comparison target in the parameter expansion table 16 is NUME as shown in FIG.
The attribute check unit 19 checks whether the content of the check target portion includes illegal decimal.

When it is determined that there is an error in the content of the check target portion in the check target data record
(Step S53 is YES) is attribute check section 19
Holds the contents and the item name of the reference data record corresponding to that part internally (step S54), and then checks the next contents of the contents passed from the check target part acquisition unit 18. (Step S52).
If there is no error in the content (step S53 returns N
O) checks the next content out of the content passed from the check target portion acquiring unit 18 (step S).
52).

When the above-described processing is performed on all the contents of the check target portion passed from the check target portion acquisition unit 18 (YES in step S55), the attribute check unit 19 sets the reference corresponding to the errored portion. It is determined whether the contents and the item names of the data record are held (step S56).

When it is determined that the data is not stored
In (NO in step S56), the data record currently processed, which is passed from the parameter expansion table 16, is passed to the result output control unit 20 (step S61).

If it is determined that the data is held (YES in step S56), the held contents, the item name, and the value of the variable i (the relative number of the erroneous data record) are used as the summary information as a result. The information is passed to the output control unit 20 (step S57), and the held contents and item names are cleared (step S58). Further, an attribute check unit 1
No. 9 refers to the operation flag of the parameter expansion table 16 and determines whether or not initialization of the contents having an error is instructed (step S59). That is, when the operation flag is C or CS, it is determined that initialization is instructed.

If it is determined that the initialization has not been instructed (NO in step S59), the data record having the error is passed to the result output control unit 20 as it is.
(Step S61) If it is determined that the initialization is instructed, the contents of the errored portion of the data record currently processed are initialized to the contents having no attribute error (for example, all 0). Then, the initialized data record is passed to the result output control unit 20 (step S60).

After that, the attribute check unit 19 enters a waiting state and waits for a next check result from the result output control unit 20 (step S62).

When the summary information or the data record is passed, the result output control section 20 determines whether the summary information or the data record has been passed, as shown in the flowchart of FIG. 12 (step S71). ).

When it is determined that the summary information has been passed, the result output control unit 20 determines whether or not the summary information flag is “1” with reference to the parameter expansion table 16 (step S72). If it is determined that the value is "0", the process waits until a data record is passed from the attribute check unit 19 (step S74). If it is determined that the value is "1", the summary information is output to the output device 5. (Step S73), and waits for a data record to be passed from the attribute check unit 19 (step S74).

When the data record is passed from the attribute check unit 19, the result output control unit 20 outputs the data record to the output data file 6 (step S75), and then the attribute check unit 19 receives the next check result. Is requested (step S76).

If it is determined in step S71 that the data record has been passed, the result output control unit 20
Refers to the operation flag in the parameter expansion table 16 and determines whether or not it is instructed to output a data record having no error (step S78). That is, when the operation flag is “C” or “0”, it is determined that an instruction to output a data record having no error is given. If it is determined that the output of the data record having no error is instructed, step S
75 is executed, otherwise step S76.
Is processed.

The attribute check unit 19 is used by the result output control unit 2
When the next check result is requested from 0 (FIG. 11, step S62), the check target part acquisition unit 18 is requested to obtain information about the next data record (step S63).

When the information about the next data record is requested from the attribute check unit 19 (step S43 in FIG. 10), the check target part obtaining unit 18 requests the data reading unit 17 to read the next data record. Yes (step S44).

When there is a read request for the next data record from the check target acquisition unit 18 (step S34 in FIG. 9), the data reading unit 17 performs the same processing as described above (steps S31 to S34).

When the above-described processing is performed by the data reading unit 17, one data record is passed from the data reading unit 17 to the check target part obtaining unit 18. When the data record is passed from the data reading unit 17 (FIG. 10, step S45), the check target part obtaining unit 18 performs the same processing as described above (steps S41 to S44).

By performing the above-described processing in the check target part obtaining unit 18, the attribute checking unit 19
The contents of the part to be checked, the item name, and the data record currently being processed are passed. Attribute check unit 19

After incrementing the value of the indicated variable i by 1 (step S65), the same processing as described above is performed (steps S52 to S63).

When the above-described processing is performed by the attribute check unit 19, if there is an error in the data record currently being processed, the summary information and the data record are passed to the result output control unit 20 as a check result. ,
If there is no error, the data record is passed to the result output control unit 20 as a check result. Result output control unit 20
When the check result is passed from the attribute check unit 19 (FIG. 12, step S77), the same processing as described above is performed.
(Steps S71 to S76) are performed.

Thereafter, the data reading unit 17, the check target part obtaining unit 18, the attribute checking unit 19, and the result output control unit 20 repeat the same processing as described above.

When the data reading unit 17 detects the end of the check target record storage file 4 (FIG. 9, step S32 is YES), the data reading unit 17
Notifies the check target portion acquisition unit 18 of the end (FIG. 9, step S35), and the data reading unit 1
7 ends the processing.

Further, the check target portion acquisition unit 18 receives the end notification from the data reading unit 17 (FIG. 10,
(Step S45) After notifying the attribute check unit 19 of the end (Step S46), the process is ended, and the attribute check unit 19 checks the part to be checked 1
When the end notification is received from 8 (step S6 in FIG. 11).
4) After notifying the result output control unit 20 of the end (step S66), the process ends. Further, upon receiving the end notification from the attribute checking unit 19 (FIG. 12, step S77), the result output control unit 20 ends the processing.

Various operations can be performed by the data check device 1 depending on the contents of the check operation designation parameter description 3. For example, among data records created by the system A, data records having no attribute error As is, the data record with the attribute error is initialized after the content of the part where the attribute error is detected,
By outputting the data to the check target record storage file 4, the data record created in the system A has a portion that causes a data exception in the system B, and the data record created in the system A remains unchanged. Then, even if it is not possible to perform a test of a function related to the data record processing of the system B,
By using the check target record storage file 4, it is possible to perform a test or the like of a function related to the data record processing of the system B.

[0089]

As described above, the present invention is based on the record structure definition information indicating the structure of the reference data record and the check operation specification parameter description 3 for specifying the attribute of the item to be checked. Of the data record for which the attribute check is to be performed, and the attribute check of the data record to be checked is performed based on the position in the record, so that the identification in the data record can be performed without burdening the user. There is an effect that the attribute check can be performed only for the attribute.

Further, according to the present invention, the check target data record having no attribute error is output to the output data file as it is, and the content of the data record having the attribute error is changed to the content having no attribute error. Since the data record is output to the output data file, even if the data record created in one system includes a part that causes an attribute error in another system, There is an effect that it becomes possible to create a data record that can be used in a test or the like in the other system from a data record created in a certain system.
